The Origin and Production of Tall Oil Fatty Acid
Tall oil fatty acid, often abbreviated as TOFA, is derived from tall oil, a byproduct of the kraft pulping process used in
paper production. This process involves the extraction of cellulose fibers from wood, primarily pine trees. The name
"tall oil" comes from the Swedish word "tallolja," which means pine oil.

The production of tall oil fatty acid involves several stages:

1. Crude Tall Oil Extraction: During the kraft pulping process, wood chips are cooked in a solution of sodium hydroxide
and sodium sulfide. This treatment separates the cellulose fibers from lignin and other wood components. The resulting
black liquor contains crude tall oil, which is skimmed off the surface.

2. Distillation: The crude tall oil undergoes fractional distillation to separate its components. This process yields three
main fractions: tall oil fatty acids, tall oil rosin, and distilled tall oil.

3. Purification: The tall oil fatty acid fraction is further refined to remove impurities and achieve the desired quality for
various applications.

The composition of tall oil fatty acid can vary depending on the wood source and processing methods. Typically, it
contains a mixture of fatty acids, including oleic acid, linoleic acid, and palmitic acid. This unique composition
contributes to its versatility and makes it a valuable raw material for numerous industries.

Chemical Properties and Composition of Tall Oil Fatty Acid
Understanding the chemical properties and composition of tall oil fatty acid is crucial for appreciating its wide range of
applications. TOFA is a complex mixture of fatty acids, with its exact composition varying based on factors such as the
wood source, geographical location, and processing methods.

The primary components of tall oil fatty acid include:

1. Oleic Acid: This monounsaturated fatty acid typically makes up the largest portion of TOFA, usually ranging from 40-
50%. Oleic acid contributes to the liquid nature of TOFA at room temperature and its stability against oxidation.

2. Linoleic Acid: A polyunsaturated fatty acid, linoleic acid is the second most abundant component in TOFA, typically
comprising 30-40% of the mixture. It enhances the drying properties of TOFA, making it valuable in coatings and paints.

3. Palmitic Acid: This saturated fatty acid usually accounts for 5-10% of TOFA. It contributes to the overall stability of
the mixture and its performance in various applications.

The unique chemical structure of tall oil fatty acid, characterized by long hydrocarbon chains with carboxyl groups,
imparts several important properties:

- Low Volatility: TOFA has a high boiling point, making it suitable for applications requiring thermal stability.
